BATT-3 is a universal battery pack, and can be used with Dry Baths, Slim PCR Cyclers and G50/ G30 motor-driven tissue grinders. It is an ideal accessory for field applications. Also, it can be used as an alternative power source for a lab when the electricity is not stable. The power input goes from the power adapter through the battery pack to the equipment. When the power is shut off for some time, the battery pack can keep the equipment working for several hours.
